Big Finish Productions have announced that they will be hosting a one-day internet-based event on Saturday 3 July 2010, beginning at 00:00 hours until midnight at www.bigfinish.com.

The centerpiece of the day is an exclusive, one-off massive sale during which the first 50 Doctor Who main range titles will be available to buy for just Â£5 each, on CD or download. This price is valid for the stated 24 hours only. So, if youâ€™re missing anything from The Sirens of Time up until Zagreus, this is a unique opportunity to catch up.

â€œWeâ€™re aware that some Doctor Who fans have never tried Big Finish,â€ says executive producer Jason Haigh-Ellery. â€œAnd weâ€™re also aware that some people have the more recent titles but have never dipped into the back catalogue. This is a chance for them to do so.â€

For anyone who already has those 50 titles, thereâ€™s still plenty to enjoy on Big Finish Day. Weâ€™ll be releasing â€“ for free, and for one day only â€“ episode one of Cobwebs, the start of the new trilogy that reunites the Fifth Doctor with Tegan, Turlough and Nyssa for the first time in 26 years.

â€œWe were thrilled that Janet has elected to join the Big Finish fold,â€ says executive producer Nicholas Briggs, â€œand I can promise that this trilogy of Cobwebs, The Whispering Forest and The Cradle of the Snake will delight all fans of that era. On Big Finish Day, youâ€™ll get a chance to hear an early preview of that brilliant TARDIS crew in action.â€

As well as additional sale items, the Big Finish website will be offering a selection of wallpapers for download, featuring some of Alex Mallinsonâ€™s most inspired artwork.
